How do adult stem cells differ from embryonic stem cells?

Answer:

A. Adult stem cells have unipotency, and embryonic stem cells have pluripotency.

Explanation:

The basic difference between a stem cell and a totipotent cell is that a stem cell has the potential to regenerate itself apart from producing other cells which are alike, for example hematopoietic stem cell. In contrast to this, a totipotent cell has the potential to develop into an entire organism but it cannot regenerate itself, for example zygote. Zygote can produce the entire organism but once zygote divides to form an embryo it can never become a zygote again.

In the early embryonic stages in mammals when the zygote divides to form 8 celled morula, each of the cell of morula retain its power of regeneration of an entire individual if allowed to develop separately but with advancement in development, the stem cells start to loose their potential to develop into the entire individual and they are confined to only pluripotency which means that they can only form an embryo and some parts of extra embryonic membranes not all of them.

Further when gastrula stage arrives, the power of cells to regenerate reduces even more and become restricted to only multipotency.

In the end, when the entire individual is developed the adult stem cells remain the only cells which have power of regeneration and they have unipotency which means that they can regenerate only one type of tissue. For example, skin cells are unipotent cells which can only regenerate skin.

Natural selection causes A. changes in allele frequencies within a population. B. changes in the mechanism of inheritance. C. th
wolverine [178]

Answer:

Natural selection causes change in allele frequencies within a population.          

So option A is correct one.

Explanation:

Natural selection generally  work  on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.

A neuron with a cell body located in the CNS whose primary function is connecting neurons is called a ________.
brilliants [131]

Answer:

Intermediate neuron

Explanation:

Interneurons are the "middle man", neither a sensory or motor nueron, that creates neurial circuits, connecting a broad class of neurons in the spinal cord and brain. They enable communication from motor and sensory neurons in the central nervous systems and are classified into two groups; relay and local interneurons. Through neurial circuits, the brain is able to manage and deal with complex stuff such as decision-making and learning.

A plasmid _____________________________ . A. can confer antibiotic resistance to a bacterium. B. is a single-stranded circular D
hodyreva [135]

Answer:

The correct answer will be option A.

Explanation:

The bacteria organize its genetic material in the single circular chromosome suspended in the cytosol along with additional circular double-stranded DNA molecule called plasmid.

The plasmid is present as a separate structure in the cytoplasm which performs important functions during stressful conditions in the bacteria like providing antibiotic resistance to the bacteria, formation of filial factors during conjugation and many others.

The plasmid which confers resistant to the bacteria is known as the R-plasmid. The R-plasmid consists of r-determinants which confers antibiotic resistance to the bacteria and resistance transfer factor (RTF) which helps in plasmid transfer.

Thus, option A is the correct answer.
